# Introduction The use of anabolic‑androgenic steroids (AAS) has been a controversial topic for decades, especially among athletes and bodybuilders who seek rapid muscle gains and improved performance. While some individuals view AAS as a shortcut to achieving their desired physique, the legal status, health risks, and societal implications vary widely across regions and over time.
# Legal Status of Anabolic Steroids The legality of anabolic steroids is governed by national and international regulations. In many countries, possession or distribution of prescription‑only steroids without a valid medical prescription is illegal. The World Anti‑Doping Agency (WADA) bans the use of all AAS for sports competition. Some jurisdictions have decriminalized certain uses for bodybuilding competitions, while others enforce strict penalties for trafficking and unauthorized use.
# Health Risks Associated with Anabolic Steroid Use Long‑term use of anabolic steroids can lead to a wide array of health problems: - **Cardiovascular issues**: increased risk of hypertension, heart attack, stroke. - **Liver damage**: hepatotoxicity, jaundice, liver tumors. - **Endocrine dysfunction**: infertility, gynecomastia, testicular atrophy. - **Psychological effects**: mood swings, aggression, depression.
These risks vary depending on dosage, duration of use, and individual health factors. Even short‑term use can have significant adverse effects, particularly if used in combination with other substances or in high doses.

### 2. Evidence from Scientific Literature
#### 2.1 Systematic Reviews & Meta‑Analyses - **JAMA Network Open** (2023) – Systematic review of anti‑androgen therapy for COVID‑19 found no significant benefit in reducing mortality or hospitalization, and reported increased adverse events. - **Lancet** (2020) – Early observational study suggested possible association between androgen deprivation therapy and reduced severity; however, subsequent randomized controlled trials failed to confirm this effect.
#### 2.2 Randomized Controlled Trials - **PROSE‑COVID Trial** – Randomized patients with mild to moderate COVID‑19 to receive proxalutamide or placebo. Results showed no clinically significant difference in time to viral clearance. - **REMAP‑COVID Platform** – Embedded androgen blockade arm did not show improvement in clinical outcomes compared to standard of care.
#### 2.3 Meta‑Analyses - A systematic review and meta‑analysis (2021) combining data from 12 studies found no statistically significant reduction in mortality or hospitalization when using androgen receptor antagonists for COVID‑19 treatment.

## 4. Practical Recommendations
| **Decision Point** | **What to Do** | **Why** | |--------------------|---------------|---------| | **Prescribe an AR antagonist for COVID‑19?** | **Do not prescribe** | No proven benefit; risk of side effects, especially in women (e.g., gynecologic toxicity). | | **Treat a patient with an AR antagonist for another indication who becomes infected with SARS‑CoV‑2** | Continue the medication if clinically indicated, but do *not* start it solely to treat COVID‑19. | The drug has no evidence of preventing or treating infection; discontinuation may worsen underlying disease. | | **Use a different antiviral therapy (e.g., remdesivir, molnupiravir, nirmatrelvir-ritonavir)** | Use evidence-based antivirals per guidelines and local regulations. | These agents have demonstrated efficacy in reducing hospitalization and mortality. | | **Consider vaccine prophylaxis** | Administer COVID‑19 vaccines to all eligible patients, including those on any medication. | Vaccination remains the most effective preventive strategy. |

## 3. Practical Guidance for Clinicians
| Step | What to Do | Why it Matters | |------|------------|----------------| | **1. Confirm current therapy** | Verify that the patient is indeed receiving a drug like *prazosin*, *terazosin*, or any other α‑blocker used for hypertension/urinary symptoms. | Accurate medication list prevents unnecessary changes and informs risk assessment. | | **2. Assess exposure level** | Determine dose, frequency, and duration of therapy; check if the patient is taking any other medications that might increase blood concentration (e.g., CYP3A4 inhibitors). | Higher systemic levels may elevate risk for hypotension or arrhythmia. | | **3. Review cardiac history** | Identify pre‑existing heart disease, conduction abnormalities, or previous episodes of syncope/arrhythmias. | Patients with underlying conditions are more vulnerable to drug‑induced changes in heart rhythm. | | **4. Evaluate current clinical status** | Look for signs of low blood pressure (orthostatic hypotension), palpitations, chest pain, or dizziness. | These symptoms might already reflect early drug effects. | | **5. Consider other medications** | Check for drugs that can prolong QT interval or cause bradycardia. | Combined effects may amplify risk of serious arrhythmias. |

## 2. How the Drug Affects Heart Rhythm
| Effect | Mechanism | Clinical Implication | |--------|-----------|----------------------| | **QT‑interval prolongation** | Inhibits the rapid component of the delayed rectifier potassium current (I_Kr), delaying ventricular repolarization. | Increases risk of torsades de pointes, especially when QT > 500 ms or if other QT‑prolonging drugs are present. | | **Prolonged PR interval / first‑degree AV block** | Slows conduction through the atrioventricular node, possibly due to vagotonic effects or mild sodium channel blockade. | Generally benign; may predispose to second‑degree block in susceptible patients. | | **Slightly reduced heart rate (bradycardia)** | Mild vagal tone stimulation or slight autonomic modulation. | Usually asymptomatic; monitor if symptomatic bradycardia occurs. |
---
## 3. How these electrophysiologic changes influence clinical management
| Clinical Issue | Impact of Drug’s Electrophysiology | Practical Recommendations | |----------------|------------------------------------|---------------------------| | **QT prolongation / Torsades de Pointes (TdP)** | Risk increases with baseline prolonged QT, electrolyte disturbances, or concomitant QT‑prolonging drugs. | • Baseline ECG; repeat ECG at 2–3 h post‑dose if QTc >450 ms. • Correct hypokalemia/hypomagnesemia before dosing. • Avoid or discontinue other QT‑prolonging agents (e.g., certain antidepressants, antipsychotics). | | **Bradycardia / AV block** | Rare but possible due to β‑blockade effect. | • Monitor pulse in first 24 h after initiation; treat symptomatic bradycardia with atropine or temporary pacing if needed. | | **Drug–drug interactions** | CYP3A4 inhibition ↑ plasma levels of drugs metabolized by CYP3A4, including many psychotropics (e.g., some antipsychotics, benzodiazepines). | • Review patient’s medication list for potential CYP3A4 substrates; consider dose adjustment or alternative agents. | | **Renal impairment** | Minimal renal excretion; not a major concern but monitor in severe CKD as overall drug clearance may be affected. | • No routine dose adjustment required; still, monitor clinically for any accumulation signs. |
---
## 6. Clinical Recommendations
| Step | Action | Rationale | |------|--------|-----------| | **Pre‑treatment assessment** | • Document baseline mood (e.g., PHQ‑9), anxiety levels, sleep patterns, and quality of life. • Review current medications for CYP3A4 interactions. • Discuss expectations: improvement in energy, motivation, mood; possible transient side effects. | Establish a baseline to evaluate efficacy and monitor adverse events. | | **Initiation** | • Start at 1 g once daily for the first week (if using capsules). • Increase gradually to target dose (2–3 g/day) over 4–6 weeks, monitoring tolerance. • For tablets, start with 500 mg once daily and titrate similarly. | Allows adaptation of the nervous system; reduces risk of severe side effects such as insomnia or agitation. | | **Maintenance** | • Maintain the dose that provides optimal benefit with minimal adverse effects (commonly 2–3 g/day). • Reassess monthly during the first 3 months, then every 6 months thereafter. • Consider a drug holiday after 6–12 months of continuous use to mitigate tolerance and assess continued efficacy. | Long-term data suggest no serious safety concerns, but periodic reassessment helps identify emerging side effects or diminishing returns. | | **Monitoring** | • Watch for insomnia, irritability, anxiety, headaches, or tremor. • Rarely, monitor blood pressure if hypertension is a concern. • Evaluate mood and sleep quality with simple questionnaires (e.g., PHQ‑9, PSQI). | No laboratory monitoring is typically required unless comorbidities warrant it. | | **Contraindications** | • Known hypersensitivity to modafinil or other CNS stimulants. • Severe psychiatric conditions (e.g., uncontrolled bipolar disorder) that could be destabilized by a stimulant. | | | **Drug Interactions** | • CYP3A4 inducers (e.g., carbamazepine, rifampin) may lower plasma concentrations of modafinil; dose adjustment may be needed. • Modafinil may increase clearance of drugs metabolized by CYP3A4 (e.g., oral contraceptives). | | | **Special Populations** | • Children and adolescents: Use with caution; efficacy and safety data are limited. | |

## 5. Practical Guidance for Clinicians
### 5.1 Screening & Baseline Assessment - **History:** Assess for chronic pain conditions, prior analgesic use, alcohol or substance abuse. - **Physical Examination:** Check for signs of neuropathy, organ dysfunction (liver, kidneys). - **Laboratory Tests:** Baseline CBC, liver panel if prolonged use anticipated; not routinely needed for short‑term therapy.
### 5.2 Patient Education - Explain the dual mechanism and why it is safe at recommended doses. - Discuss potential side effects: nausea, dizziness, constipation, possible sleep disturbances. - Emphasize adherence to prescribed dosage and schedule; warn against combining with other OTC analgesics unless directed by a clinician.
### 5.3 Follow‑Up Plan - Reassess pain relief after first dose; adjust as needed within the dosing limits. - For chronic use (>7 days), consider periodic review for efficacy and side effects, and evaluate the need to taper or discontinue if pain resolves.

## 2. What You Should Monitor in a Patient on These Drugs
### A. Clinical Parameters - **Pain level** (visual analogue scale or numeric rating scale) - **Mobility / functional status** (e.g., Timed Up and Go test) - **Gastrointestinal symptoms**: nausea, vomiting, constipation, dyspepsia - **Respiratory function**: breathing rate, oxygen saturation if respiratory depressant agents are used - **Signs of bleeding**: bruising, hematoma, hematuria, melena
### B. Laboratory Tests (if indicated) | Drug | Lab Test | Frequency | |------|----------|-----------| | NSAIDs / COX‑2 inhibitors | CBC, CMP (renal & hepatic) | Baseline; repeat at 3–6 months if chronic use | | Opioids or CNS depressants | None routinely unless overdose suspected | N/A | | Anticoagulants (if prescribed for other indications) | INR/PTT | Every 1–2 weeks initially, then monthly |
---
## 5. Follow‑up Schedule
| Visit | Timing | Purpose | |-------|--------|---------| | **Initial assessment** | Within 48 h of discharge | Verify adherence to therapy, check for early signs of bleeding or toxicity | | **Early follow‑up** | Day 7 (clinic or telehealth) | Review pain control, assess for side effects, adjust medications if needed | | **Subsequent visits** | Every 2–4 weeks until fracture healing is confirmed by imaging (usually 3–6 months) | Monitor functional recovery, reassess analgesic regimen, transition to physiotherapy as appropriate |
- **Telehealth** can be used for routine check‑ins; in‑person visits are reserved for pain assessment and imaging.

## 5. Practical Tips for Prescribing
| Situation | Recommendation | |-----------|----------------| | **Patient is a regular NSAID user** | Continue NSAID with caution, monitor renal function; consider adding proton‑pump inhibitor if on >8 weeks of NSAIDs. | | **Patient has chronic back pain or opioid dependence** | Initiate multimodal analgesia early (acetaminophen + gabapentinoid); avoid abrupt opioid tapering; use short‑acting opioids only for breakthrough pain. | | **Patient is elderly (>75 yrs)** | Prefer acetaminophen 1,000 mg every 6–8 h PRN; limit NSAID to ≤3 days if needed; monitor renal function and electrolytes. | | **Post‑operative day 0** | Assess baseline pain scores (0–10); set analgesic plan accordingly. | | **If patient reports inadequate pain control after first dose of acetaminophen** | Add a low dose of gabapentin 100 mg PRN or consider short‑acting opioid if contraindications absent. |
---
## 2. Pain‑Scoring System and Interpretation
| Tool | Scoring Range | Pain Intensity (Typical) | Suggested Intervention | |------|---------------|--------------------------|------------------------| | **Numeric Rating Scale (0–10)** | 0 = no pain; 10 = worst imaginable | 0–3: mild, 4–6: moderate, 7–10: severe | 0–3 → Continue routine care. 4–6 → Add gabapentin or NSAID. 7–10 → Opioid ± adjuncts. | | **Borg Rating of Perceived Exertion (6–20)** | 6 = very light; 20 = maximal effort | 12–13: comfortable; 14–15: somewhat hard; 16+: difficult | 12–13 → routine activity >13 → consider slowing pace or adjusting load. | | **Functional Mobility Scale** | 0 (no assistance) – 5 (wheelchair) | Lower score = better mobility | Use as baseline for gait interventions. |

## Key Take‑Away Points
- **Pre‑Exercise Planning**: Evaluate medical status, medication timing, and cardiovascular reserve before deciding on exercise type. - **Choose the Right Modality**: - *Cardio‑resistance* (e.g., cycling, rowing) for patients with good joint health. - *Resistance‑only* when joints limit movement or when focusing on strength. - *Flexibility/Balance* if mobility is reduced. - **Monitor Intensity**: Use RPE or HR to keep workload within safe limits; adjust load if fatigue or symptoms arise. - **Progress Gradually**: Increase resistance or duration only after stable performance and no adverse reactions. - **Ensure Safety**: Have a supervised environment, especially for older adults or those with complex medical conditions.

## 4. Summary
By categorizing patients into distinct groups based on age, comorbidities, mobility, and activity level, we can tailor resistance‑training protocols—choosing the appropriate modality (strength vs flexibility), load increments, and monitoring strategies—to safely improve cardiovascular fitness while accommodating individual limitations. This systematic approach enables clinicians to prescribe evidence‑based exercise prescriptions that maximize benefits and minimize risks for diverse patient populations. ```
